GeForce GT 430 (OEM) vs Radeon HD 5570

Intro

Compare all of that to the Radeon HD 5570, which comes with a core clock speed of 650 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
GeForce GT 430 (OEM)		60 Watts
	Difference: 17 Watts (40%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon HD 5570 will be a bit (approximately 16%) more effective at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

Radeon HD 5570		13000 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 1800 (16%)

Pixel Rate

The Radeon HD 5570 is much (more or less 86%) more effective at FSAA than the GeForce GT 430 (OEM), and should be able to handle higher resolutions better. (explain)

Radeon HD 5570		5200 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 2400 (86%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
